Jared bets on the number 7 for each of 100 spins of a roulette wheel. Because P(7) = 1/38 he expects to win two or three times. What is the probability that Jared will actually win two or more times? This was a quiz question I answered incorrectly, I want to understand how to get it if a similar question is on the mid term.
